PGP alternative without key exchange
Share encrypted content without the PGP hassle: no key pair, no keyserver, no software. Encrypted client-side in the browser (AES-256-GCM), as a one-time link — zero-knowledge.
What zero-knowledge gives you
- No key exchange, no keyserver, no software
- AES-256-GCM client-side, key stays in the URL fragment
- Read-once and expiry instead of permanently decryptable mail
- Optional recipient approval as an extra layer
Where this replaces PGP, and where it does not
PGP has been the reference for encrypted messaging since 1991 and remains the right answer for signed, long-lived correspondence. Its cost is setup: both sides generate a key pair, exchange public keys, and verify that the keys really belong to whom they claim.
For a single confidential transfer that overhead rarely gets paid, and the message ends up going in plaintext instead. A browser-encrypted one-time link removes the setup entirely — the key is generated per message and travels with the link, so the recipient needs no software and no prior arrangement.
What you give up is identity. There is no signature proving who wrote the message and no durable key to build trust on over time. For recurring correspondence between technical parties, PGP remains the better fit; the two approaches solve different halves of the problem and combine well.
Frequently asked questions
Is this as secure as PGP?
It uses strong modern cryptography (AES-256-GCM, client-side). Unlike PGP there are no durable signed identities; for confidential one-time delivery without key exchange it is much simpler.
Does the recipient need to install PGP?
No. The recipient just opens the link in a browser. No key exchange, no software.
